These are some post mortem notes from the TAs about this assignment.
There are several things that need changing: The generateVanityKey problem should be in its own file.
The section entitled Generate a Vanity Key should be renamed to Generate Vanity Address
A small go program that computes the fibonacci sequence of 23 or so should be a required problem
The funding of the vanity address transaction should also send coins to other sutudents. And there should be a question about the total coins input and the total coins output.
The command line script could be more verbose in its output and -address should be -toaddress
